BORS (Barrett Optical Ranging System) is an integrated electronic ballistic computer that mounts directly on the riflescope and couples with the elevation knob. In other words, it’s like having an army of ballisticians behind every shot. By taking care of all the science, BORS frees the user to focus on the thrill of putting lead on target.

The computer BORS is put into action by simply turning the elevation knob until the LCD displays the target’s range. Three internal sensors automatically calculate the ballistic solution. BORS compensates for temperature, changes in barometric pressure and aiming on an upward or downward angle. BORS even determines if the rifle is canted. In fact, the only thing this portable mastermind can’t do is pull the trigger.

The BORS kit includes the Barrett Ballistic PC Software and a BORS data cable that allows the user to program custom loads on their personal computer and transfer them directly to their BORS.
